9mm Commander at 25 Yards

Thanks for clearing that up. Thought my "memory nerve" was messing up again!

Colt 9mm barrels have chambers that are very sensitive to ammo sizing for good accuracy. At least all the ones I played with in the 80's and 90's did. Ditto for the old 9mm 39/59 barrels from S&W.

I had a fairly well fitting S&W 9mm barrel in a 39, and it shrank groups to 1/3 the size by the addition of the BarSto barrel (no longer made). That gun got stolen by UPS when I sent it out for hard chroming. @#$@#

The 9's run finicky on ammo when the chambers are cut generously. More finicky than even the .38-Super.

By way of comparison the .45ACP is forgiving, it seems by its very nature. Maybe its the straight wall vs taper of the 9mm?

The BarSto made a significant difference.

Now it's up to me.
